Abstract
The texture incorporated during cold rolling of maraging steel persists even when the samples are annealed at temperatures close to the melting point. The texture influences the microstructural developments observed following aging, which in turn affects the magnetic properties of maraging steel. The maximum coercive field, observed after aging at about 700°C, increased from about 11 140 A m−1 in the as rolled and aged condition to about 14 720 A m−1 in the specimen annealed at 1000°C before aging. The corresponding saturation magnetisation values also increased from about 1·040 to about 1·300 T. The prior annealing affects the morphology of the precipitates as well as the reverted austenite.
